RESEARCH ON USER AUTHENTICATION TECHNIQUE USING WEB PORTAL INTERGRATED FIREWALL AND RADIUS SERVER FOR WIRELESS NETWORKING SYSTEM OF THAI NGUYEN UNIVERSITY OF INFORMATION AND COMMUNICATION TECHNOLOGY

Abstract

Today, wireless networks are extremely popular in all offices, industrial parks, homes, and schools. However, due to the nature of network technology, an authentication solution is needed to prevent unauthorized access. On the other hand, at universities, due to the large number of users, the network security solution using WPA password becomes not feasible. Therefore, we propose a solution to authenticate wireless network security with Captive Portal technology combined with RADIUS authentication method. Captive Portal is a technology that allows controlling and restricting all access using HTTP protocol from the browser. Users on the network will be redirected to a portal for authentication before being allowed to access the internet. RADIUS is a network service that enables authentication and authorization for users on the network. This article will present and simulate the combination of Captive portal feature on pfsense firewall with an active directory server to provide RADIUS user authentication service for ICT - Thai Nguyen university's wireless network.
